I end up about 35 on 250mg test. Which has my blood levels at 1500 ng/dl, I like to roughly follow the 1:50 esto to test ratio alot of gear users have suggested. In this scenario that would suggest I need 30 estro to balance out 1500ng/dl test, but when I do use an AI on a cruise it is basically impossible for me to get the dosing right. It ends up crashing (well at least I get the symptoms of crashed estro) whenver I try.
When I first started using gear I always tried to keep estro near the suggested range, 20-40 or thereabouts? (don't quote me on the exact range idr offhadn) but I found I would end up getting low estro symptoms even with a estro in range. For example on 750mg test I got an estro reading back at 35, and felt like I had bottomed out my e2. dick issues, lethargy, joints felt horrible, so I backed off the AI. In a way it makes sense as the suggested range is for people wiht physiological test levels, so of course they would also ideally have less estro.
I don't mean to suggest everyone is the same as me, but I feel and function so much better (in all areas of life, gym, sexually, well being) following this sort of guideline.
